Matter straight up doesn't work on lubuntu 24.10

[alanciuch]

Hello I tried to install matter theme on lubuntu 24.10, but it just doesn't work. My grub menu shows up but it always looks like a black and white terminal. I tried reinstalling (with sudo of course), changing the icons, using different examples from the bottom of the GitHub page, editing /etc/default/grub myself, but nothing works. Every time I reboot I just get the boring old grub. Can someone help?

That is weird, I am on Ubuntu 24.10 and it does work, should work on lubuntu as well.

Can you share the full output you get from the different commands in the quickstart guide?

Hi, I attach a link to a video of me trying to install matter using your quick start tutorial.

Also if you want I can try to install lubuntu in a virtual machine and try it there.

Edit: I also forgot to say that I installed grub customizer and even there it says that the matter theme is enabled

Your first permission denied error is reported in #84, for some reason our sudo prompt is failing on newer versions of Ubuntu. Using sudo as you did is the right thing to do for now.

Can you run the same again and share a copy of these 4 files:

1. /etc/default/grub
2. /boot/grub/grub.cfg
3. /usr/sbin/grub-mkconfig
4. /etc/grub.d/99_matter

In particular, strings like --class microsoft-windows or --class ubuntu should appear in /boot/grub/grub.cfg.

Additionally, please also share your output when executing sudo update-grub.
